The admonition I run into again and again, attributed to such lights as Thelonius Monk and Louis Armstrong is "play the melody." Of course you will syncopate it, put a little ornamentation here and there, but simple is fine That covers soloing pretty well, but what about comping? Guitarists with jazz chops rarely hang on the same voicing for more than a ...
One golden rule. Play less. Lay out. Leave space. If there's someone in the group who CAN play jazz, allow him room to do it. And have fun! Let the music go where it will. Don't rehearse it to death. If it's your turn to play a solo, the melody will be just fine.
